OVENHGRTE.

QPECFICATION forming part of Letters Patent No. 301,372, datediuly I, 1884.

Application led September 14, 1883. (No model.)

El? all when@ t nea/y eoncern:

Be itknown that I, WILLIAM H. Keir-ino, of Boston, in the county of Suliolk, State of Massachusetts, have invented a certain new and useful Improvement in Oven Grates, of which the following1 is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in Whieln- Figure l is an isoinetrieal perspective view, and Fig. 2 a vertical longitudinal seetion.

Like letters and iigures of reference indicate corresponding parts in the different iignres ot' the drawings.

ln baking pies, puddings, 8m., in the ovens of ordinary cooking-stoves they are liable to burn or to be baked unevenly on account of the heat being greater next the nre, or on one side or' the oventhan it is on the other.

This invention relates to rotary oven-grates designed to obviate this difficulty.

The objects of the invention are to provide a grate of this character which may be readily applied to and removed from any ordinary oven, and which is simple and cheap.

To these ends the invention consists in an oven-grate of peculiar construction, as hereinafter described. and claimed.

ln the drawings, A represents the body or base of the grate, and 13 the table. The base is square, and consists of a thin iiat pieee of iron having` a series of elongated slots, and provided With the legs m, and an upwardly prog` eating centrally-arranged boss, d, the legs and hub being east integral with the base. The table is round and provided with aseries of radial slot-s, f, and a recessed hub, 12W-bieb is Centrally pivoted to the boss CZ, so as to revolve freely thereon. The table is elevated yslightly above the base, so as to permit the or pudding' to be balred is placed on the table B, the table being turned from time to time during the process to change the position of the pie, so as to expose all ol' its sides in regular succession to the hottest part of the oven, and thereby balie it evenly.

In nearly all eookingstoves having ovens the tire-pot is arranged at one side of the oven, thereby heating the air unequally-that is to say, the air in that part of the oven next the 'lire-pot will be heated or rareiied to a greater extent than that at the opposite side, thereby generating a Current of air Within the oven,

To direct and utilize this heated current to the best advantage is one object of niyinvention; and to that end l construct the base A with a series ol' elongated slots, x, arranged in parallelism, and niount it on the legs m, so that as the air iloivs across the bottoni of the oven and rises through the slots t it will be distributed uniformly to the plate or dish on the table B, which is provided with radial slots which serve further to distribute the eurrent.

l do not confine myself to using the grate for pies and puddings alone, as it is valuable for baking bread, cake, die., and may also be used to advantage in an ordinary brick oven, or in any Oven used for culinary purposes.

I ain aware that portable oven-grates having rotary tables are not new, broadly; but in my invention the stationary and rotary plates being` provided with slots arranged as described, the eurrentoi air is utilized to the best advantage.

Having` thus explained niy invention, what I elaini is- As a neuv article of manufacture, a portable or removable ovengrate consisting of a baseplate provided With legs, and having a series of parallel elongated slots, and a table provided With a series oi' radial slots, said table being centrally pivoted to rotate on said base, substantially as set forth.
